The heat energy required to raise the temperature of $5\,moles$ of an ideal gas to $5\,K$ at constant pressure is $600\,J$ . How much heat (in $J$ ) is required to raise the same mass of the same gas to $5\,K$ at constant volume ? (Take $R = 8.3\,J/mole-^oK$ )
A bubble from bottom of lake rises to its surface. Its volume doubles in the process. Assuming isothermal conditions, atmospheric pressure $= 75\, cm$ of $Hg$ and ratio of densities of mercury and water $40/3$. The depth of lake will be ..... $m$
Consider two containers $A$ and $B$ containing monoatomic gases at the same Pressure $(P)$, Volume $(V)$ and Temperature $(T)$. The gas in $A$ is compressed isothermally to $\frac{1}{8}$ of its original volume while the gas $B$ is compressed adiabatically to $\frac{1}{8}$ of its original volume. The ratio of final pressure of gas in $B$ to that of gas in $A$ is ...........
The amount of heat needed to raise the temperature of $4\, moles$ of a rigid diatomic gas from $0^{\circ} {C}$ to $50^{\circ} {C}$ when no work is done is ......${R}$ ($R$ is the universal gas constant)
